To forbid this, you must chance a way to create a physical roadblock between the aguacate's surface and the environ air.

There are various methods to slow down the oxidation procedure. The end of each proficiency is to downplay oxygen contact.

Citrus Juice: The high acidity of birdlime or lemon juice lower the pH point of the guacamole, which inhibit the polyphenol oxidase enzymes from act efficiently.
Plastic Wrap Press: Set plastic wrapper now against the surface of the dip obviate air pockets.
Water Bath: Bestow a thin bed of water over the surface make an gas-tight stamp, which can be poured off before serving.
